WARNINGt This chain
saw can be dangerous! Care- lessor improperuse can cause sedous or even fatal injury.
Always wear appropriate ear protection, eye protection and head protection.
Always use two hands when operating the chain saw.
Read and understand the instruction manual before
using the chain saw.
WARNINGt Contacting the guide bar tip with any object
should be avoided; tip contact may cause the guide bar to
move suddenly upward and backward, which may cause se- rious injury.
Measured maximum kickback value without chain brake for the bar and chain combination on the label.
_ WARNING: Always disconnect
spark plug wire and place wire where it can- not contact spark plug to prevent accidental starting when setting up, transporting, ad-
justing or making repairs except carburetor
adjustments. Because a chain saw is a high-speed wood- catting tool, special safety precautions must
be observed to reduce the risk of accidents. Careless or improper use of this tool can
cause serious injury. PLAN AHEAD
Read this manual carefully until you com- pletely understand and can follow all safety rules, precautions, and operating instruc- tions before attempting to use the unit.
Restrict the use of your saw to adult users who understand and can follow safety rules, precautions, and operating instruc-
tions found in this manual.
Wear protective gear. Always use steel- toed safety footwear with non-slip soles; snug-fitting clothing; heavy-duty, non-slip gloves; eye protection such as non-fog- ging, vented goggles or face screen; an approved safety hard hat; and sound bard- ers (ear plugs or mufflers) to protect your hearing. Regular users should have hear- ing checked regularly as chain saw noise can damage hearing. Secure hair above shoulder length.

OPERATE YOUR SAW SAFELY
Do not operate a chain saw with one hand. Serious injury to the operator, helpers, by-
standers or any combination of these per- sons may result from one-handed opera-
tion. A chain saw is intended for two-handed use.
Operate the chain saw only in a well-venti- lated outdoor area.
Do not operate saw from a ladder or in a tree.
Make sure the chain will not make contact with any object while starting the engine.
Never try to start the saw when the guide bar is in a cut.
Do not put pressure on the saw at the end of the cut. Applying pressure can cause you to lose control when the cut is com- pleted.
Stop the engine before setting the saw down.
Do not operate a chain saw that is dam- aged, improperly adjusted, or not com- pletely and securely assembled. Always replace bar, chain, hand guard, or chain brake immediately if it becomes damaged,
broken or is otherwise removed.
With the engine stopped, hand carry the chain saw with the muffler away from your body, and the guide bar and chain to the rear, preferably covered with a scabbard.
MAINTAIN YOUR SAW IN GOOD WORKING ORDER
Have all chain saw service performed by a qualified service dealer with the exception
of the items listed in the maintenance sec- tion of this manual. Forexample, if improp-
er tools are used to remove or hold the fly- wheel when servicing the clutch, structural damage to the flywheel can occur and cause the flywheel to burst.
Make certain the saw chain stops moving when the throttle trigger is released. For
correction, refer to CARBURETOR AD- JUSTMENTS.
Never modify your saw in any way.
Keep the handles dry, clean, and free ofoil or fuel mixture.
Keep fuel and oil caps, screws, and fas- teners securely tightened.
Use only Poulan® accessories and re- placement parts as recommended.
HANDLE FUEL WITH CAUTION
Do not smoke while handling fuel or while operating the saw.
Eliminate all sources of sparks or flame in the areas where fuel is mixed or poured. There should be no smoking, open flames, or workthat could cause sparks. Allow en- gine to cool before refueling.
Mix and pour fuel in an outdoor area on bare ground; store fuel in a cool, dry, well ventilated place; and use an approved,
marked container for all fuel purposes. Wipe up all fuel spills before starting saw.
Move at least 10 feet (3 meters) from fuel- ing site before starting engine.
Turn the engine off and let saw cool in a non-combustible area, not on dry leaves,
straw, paper, etc. Slowly remove fuel cap and refuel unit.
Store the unit and fuel in an area where fuel vapors cannot reach sparks or open
flames from water heaters, electric motors or switches, furnaces, etc.
KICKBACK
_,WARNING: Avoid kickback which
can result in serious injury. Kickback is the backward, upward or sudden forward motion of the guide bar occurring when the saw chain near the upper tip of the guide bar con- tacts any object such as a log or branch, or when the wood closes in and pinches the saw chain inthe cut. Contacting a foreign ob-
ject in the wood can also result in loss of
chain saw control.
Rotational Kickback can occur when the moving chain contacts an object at the up-
per tip of the guide bar. This contact can cause the chain to dig into the object,
which stops the chain for an instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back to- ward the operator.
Pinch-Kickback can occur when the the wood closes in and pinches the moving
saw chain in the cut along the top of the guide bar and the saw chain is suddenly stopped. This sudden stopping of the
chain results in a reversal of the chain force used to cut wood and causes the
saw to move in the opposite direction of the chain rotation. The saw is driven straight back toward the operator.
Pull-In can occur when the moving chain contacts a foreign object in the wood in the
cut along the bottom of the guide bar and the saw chain is suddenly stopped. This sudden stopping pulls the saw forward and away from the operator and could easily cause the operator to lose control of the saw.
Avoid Pinch-Kickback:
Be extremely aware of situations or ob- structions that can cause material to pinch the top of or otherwise stop the chain.
Do not cut more than one log at a time.
Do not twist the saw as the bar is with- drawn from an undercut when bucking.
Avoid Pull-In:
Always begin cutting with the engine at full speed and the saw housing against wood.
Use wedges made of plastic or wood. Never use metal to hold the cut open.
_i //'_-_- Kickback Path
_ AvoidObstructions
ClearTheWorkingArea
REDUCE THE CHANCE OF KICKBACK
Recognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise
which contributes to accidents.
Never let the moving chain contact any ob-
ject at the tip of the guide bar.
Keep the working area free from obstruc- tions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting. When cutting a branch, do not let the guide bar contact branch or other objects around it.
Keep your saw chain sharp and properly tensioned. A loose or dull chain can in-
crease the chance of kickback occurring. Follow manufacturer's chain sharpening
and maintenance instructions. Check ten- sion at regular intervals with the engine
stopped, never with the engine running. Make sure the chain brake nuts are se-
curely tightened after tensioning the chain.
Begin end continue cutting at full speed. If the chain is moving at a slower speed,
there is greater chance of kickback occur- ring.
Cut one log at a time.
Use extreme caution when re-entering a previous cut.
DO not attempt cuts starting with the tip of the bar (plunge cuts).
Watch for shifting logs or other forces that could close a cut and pinch or fall into
chain.
Use the Reduced-Kickback Guide Bar and Low-Kickback Chain specified for your saw.
MAINTAIN CONTROL
Stand to the
hand positions
Elbow locked
Thumb on underside of handlebar
Keep a good, firm grip on the saw with both hands when the engine is running and don't let go. A firm grip will help you reduce
kickback and maintain control of the saw. Keep the fingers of your left hand encir-
cling and your left thumb under the front handlebar. Keep your right hand com- pletely around the rear handle whether your are right handed or left handed. Keep your left arm straight with the elbow
looked.
Position your left hand on the front handle- bar so it is in a straight line with your right hand on the rear handle when making bucking cuts. Never reverse right and left hand positions for any type of cutting.
Stand with yoor weight evenly balanced on both feet.
Stand slightly to the left side of the saw to keep your body from being in a direct line with the cutting chain.
Do not overreach. You could be drawn or thrown off balance and lose control of the saw.
DO not cut above shoulder height. Itis diffi- cult to maintain control of saw above
shoulder height.
KICKBACK SAFETY FEATURES
_WARNING: The following features
are included on your saw to help reduce the hazard of kickback; however, such features will not totally eliminate this danger. As a chain saw user, do not rely only on safety de- vices. You must follow all safety precau- tions, instructions, and maintenance in this manual to help avoid kickback and other forces which can result in serious injury.
Reduced-Kickback Guide Bar, designed with a small radius tip which reduces the size of the kickback danger zone on the bar tip. A Reduced-Kickback Guide Bar has been demonstrated to significantly re-
duce the number and seriousness of kick- backs when tested in accordance with
safety requirements for gasoline powered chain saws as set by ANSI B175.1.
Reduced Kickback Symmetrical Guide Bar
can be caused by allowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain along the top of the guide bar. This action may push the guide bar rapidly back

toward the operator. Either of these events may cause you to lose control of the saw which could result in serious injury or even
death. DO NOT RELY UPON ANY OF THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND

Low-Kickback Chain, designed with a contoured depth gauge and guard link
which deflect kickback force and allow wood to gradually ride into the cutter. Low-
Kickback Chain has met kickback per- formance requirements when tested on a representative sample of chain saws be- low 3.8 cubic inch displacement specified
in ANSI B175.1.

CAREFULLY TO AVOID KICKBACK. Re- duced-kickback guide bars and low-kick-
back saw chains reduce the chance and magnitude of kickback and are recom-
mended. Your saw has a low kickback chain and bar as original equipment. Repairs on a
chain brake should be made by an autho- rized servicing dealer. Take your unit to the
place of purchase if purchased from a ser- vicing dealer, or to the nearest authorized master service dealer.

Position of front and rear handlebars, de- signed with distance between handles and "in-line" with each other. The spread and "in-line" position of the hands provided by this design work together to give balance and resistance in controlling the pivot of the saw back toward the operator if kick-
back occurs.
CHAIN BRAKE AND CKA ANGLE
Chain Brake, designed to stop the chain in the event of kickback.
_,WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS- SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU iN THE EVENT OF A KICKBACK. Kickback is a lightning fast ac-
tion which throws the bar and rotating chain back and up toward the operator. Kickback
angle (CKA) listed on your saw and listed inthe CKA table below represents angle of kickback your bar and chain combinations will have when tested in accordance with CSA (Cana- dian Standards Association) and ANSI stan- dards. When purchasing replacement bar and chain, considerations should be given to the lower CKA values. Lower CKA values repre- sent safer angles to the user, higher values in- dicate more angle and higher kick energies. Computed angles represented indicate total energy and angle associated without activation of the chain brake during kickback. Activated angle represents chain stopping time relative to activation angle of chain break and resulting kick angle of saw. In all cases lower CKA val- ues represent a safer operating environment
for the user. The following guide bar and chain combina- tions meet kickback requirements of CSA
Standards Z62.1, Z62.3, & ANSI B175.1 when used on saws listed inthis manual. Use of bar
and chain combinations other than those listed is not recommended and may not meet the CKA requirements per standard.

A
dll WARNING: Remove fuel cap slowly
when refueling.
FUELING ENGINE
This engine is certified to operate on un- tended gasoline. Before operation, gasoline must be mixed with a good quality synthetic 2-cycte air-cooled engine oil designed to be
mixed at a ratio of 40:1. Poulan/Weed Eater brand synthetic oil is recommended. Mix
gasoline and oil at a ratio of 40:1. A40:1 ratio is obtained by mixing 3.2 ounces (95 ml) ofoit with 1 gallon (4 liters) of untended gasoline.
Included with this saw isa 3.2 ounce contain- er of oil Pour the entire contents of this con-
tainer into 1gatlon of gasoline to achieve the proper fuel mixture.
DO NOT USE automotive oil or boat oil. These oils will cause engine damage. When mixing
fuel, foltow instructions printed on container. Once oil is added to gasoline, shake container momentarily to assure that the fuel isthorough- ty mixed. Always read and follow the safety rules relating to fuel before fueling your unit.
BAR AND CHAIN LUBRICATION The bar and chain require continuous lubri-
cation. Lubrication is provided by the auto- matic oiler system when the oil tank is kept filled. Lack ofoil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/
or discoloration of the bar. In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a small amount (5 to 10%) of #1 Diesel Fuel or
kerosene. Bar and chain oil must be free flowing for the oil system to pump enough oil
for adequate lubrication. Genuine Poulan ® bar and chain oil is recom-
mended to protect your unit against exces- sive wear from heat and friction. Poulan®
oil resists high temperature thinning. If Pou- lan® bar aod chein oil is not available, usea
good grade SAE 30 oil.
Never use waste oil for bar and chain lubd- cation.
Always stop the engine before removing the oil cap.
IMPORTANT Experience indicates that alcohol-blended
fuels (called gasoho[ or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next
season. See STORAGE section for addi- tional information.
_WARNING:
move when the engine runs at idle speed. If the chain moves at idle speed refer to CAR-
BURETOR ADJUSTMENT within this manual. Avoid contact with the muffler. Ahot muffler can cause serious burns.
To stop the engine move the ON/STOP switch to the STOP position.
To start the engine hold the saw firmly on the ground as illustrated. Make sure the chain is free to turn without contacting any object.
Use only 15"-18" of rope per pull, Hold sew firmly while pulling starter rope

CHAIN BRAKE
_WARNING: if the brake band is
worn too thin it may break when the chain brake istriggered. With a broken brake band, the chain brake will not stop the chain. The chain brake should be replaced by an autho- rized service dealer if any part is worn to less than 0.020" (0.5 mm) thick. Repairs on a chain brake should be made by an autho- rized service dealer. Take your unit to the place of purchase if purchased from a ser- vicing dealer, or to the nearest authorized
master service dealer.
This saw is equipped with a chain brake.
The brake is designed to stop the chain if kickback occurs.
The inertia-activated chain brake is
activated if the front hand guard is pushed forward, either manually (by hand) or automatically (by sudden movement).
If the brake is already activated, it is
disengaged by pulling the front hand guard
Braking function control
CAUTION: The chain brake must be checked several times daily. The engine
must be running when performing this proce- dure. This isthe only instance when the saw should be placed on the ground with the en- gine running.
Place the saw on firm ground. Grip the rear handle with your right hand and the front han- dle with your left hand. Apply full throttle by fully depressing the throttle trigger. Activate the chain brake by turning your left wrist against the hand guard without releasing your grip around the front handle. The chain should stop immediately.
Inertia activating function control
_B_WARNING: Whenperformingthe
following procedure, the engine must be turned off.
Grip the rear handle with your right hand and the front handle with your left hand. Hold the chain saw approximately 14" (35 cm) above a stump or other wooden surface. Release your grip on the front handle and use the weight of the saw to let the top of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the
brake should activate.
IMPORTANT POINTS
Check chain tension before first use and after 1 minute of operation. See CHAIN
TENSION in the ASSEMBLY section.
Cut wood only. Do not cut metal, plastics, masonry, non-wood building materials, etc.
Stop the saw if the chain strikes a foreign object. Inspect the saw and repair or re- place parts as necessary.
Keep the chain OL_of dirt and sand. Even a small amount of dirt will quickly dull a chain and thus increase the possibility of kickback.
Practice cutting a few small logs using the following techniques to get the "feel" of us- ing your saw before you begin a major sawing operation.
Squeeze the throttle trigger and allow the engine to reach full speed before cutting.
Begin cutting with the saw frame
against the log.
Keep the engine at full speed the en-
tire time you are cutting.

TREE FELLING TECHNIQUES
_WARNING: Check for broken or
dead branches which can fall while cutting
causing serious injury. Do not cut near build- ings or electrical wires if you do not know the direction of tree fall, nor cut at night since you will not be ale to see well, nor during bed weather such as rain, snow, or strong winds, etc. If the tree makes contact with any utility line, the utility company should be notified immediately.
Carefully planyoursawingoperetion inad- vance.
Clear the work area. You need aclear area all around the tree so you can have secure
footing.
The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.
Study the natural conditions that can cause the tree to fall in a particular direction.
Natural conditions that can cause e tree to fall in a particular direction include:
The wind direction and speed.
The lean of the tree. The lean of a tree might not be apparent due to uneven or
sloping terrain. Use a plumb or level to de- termine the direction of tree lean.
Weight and branches on one side.
Surrounding trees and obstacles.
Look for decay and rot Ifthetrunk is rotted, it can snap and fall toward the operator.
Check for broken or dead branches which can fall on you while cutting. Make sure there is enough room for the tree to
fall. Maintain a distance of 2-1J2tree lengths from the nearest person or other objects. En- gine noise can drown OL_a warning call. Remove dirt, stones, loose bark, nails, sta- ples, and wire from the tree where cuts are to
be made. Plan a clear retreat path to the rear and diag-
onal to the line of fall.

FELLING LARGE TREES
(6 inches in diameter or larger) The notch method is used to fell large trees.
A notch is cut on the side of the tree in the de- sired direction of fall. After a felling cut is
made on the opposite side of tree, the tree will tend to fall into the notch.
NOTE: If the tree has large buttress roots, remove them before making the notch. If us-
ing saw to remove buttress roots, keep saw chain from contacting ground to prevent dull- ing of the chain.
NOTCH CUT AND FELLING THE TREE
Make notch cut by cutting the top of the notch first. Cut through 1/3of the diameter of the tree. Next complete the notch by cut- ting the bottom of the notch. See illustra-
tion. Once the notch is cut remove the notch of wood from the tree.
Final (felling) cut here. 2 in- ches above center of notch.

Notch " i"
Second cut
After removing the wood from the notch, make the felling cut on the opposite side of the notch. This is done by making e cut about two inches higher than the center of the notch. This will leave enough uncut wood between the felling cut and the notch to form e hinge. This hinge will help pre- vent the tree from falling in the wrong direc-
tion.
Hinge holds tree on stump and helps
control fall
Closing of notch
NOTE: Before felling cut is complete, use wedges to open the cut if necessary to
control the direction of fall. To avoid kickback end chain damage, use wood or plastic
wedges, but never steel or iron wedges.
Be alert to signs that the tree is ready to fall: cracking sounds, widening of the fell- ing cut, or movement in the upper
branches.
